To all wliom it may concern! delphia, Pennsylvania, have inventedcertain Improvements in CombinationLatch- Locks, of which the followingis a Aspecification.

My invention relates tothat class of ,comiV l bination locks inv whichthe retraction of the bolt is eiected-by the knob through the medium ofthe tumblers and bolt-operating mechanism, and the projection of thebolt is dueto the action ofa spring or springs, the objects of myinvention beingto provide for the automatic ejection of the dog "iii-omthe notches of the tumblers and the dispersal. of thelatter whenthelbolt is projected' byV the action ofthe spring, and to provide, in abox or chest lock, for they automaticprojection of the bolt, theejection of the dog.` fromV the notches of the tumblers, and thedispersal of the latter when thelid is closed. These objects I attain inthe'manner hereinafter set "forth, reference being had to the"accompanying drawings, 1n which Figure 1 isa transverse sectionon the'line a-a, Fig. 3, but on an enlarged -scale, and

be governed by the, sense ofsight. The lock can, however, also beoperated by the .sense ofy hearing or the sense of touch, the knob 4beingmovable axially in the barrel 3,

`and the knob spindle dbeing also free to slide axially 'in .a Atubularyh'ub 7 projecting v Letinto suitablerecessesin the inner face A of theknob @are afpair of balls 9, or in place of theV same, fixed lugs or4studs may be formed on or secured to the inner face of the knob. Formedin or rigidly secured to the interior of the barrel V3 is an annularplate 3a, in which are. formed a seriesof conntersunk openings ordepressions 10,

correspondin in number with the figures or numbers of e dial when thelatter is employed, whereby, when the knob lV isi-moved lnwardly, theballs 9 will engage these openings or depressions and the propermovements of the knob to effect the desired adjustment of-the tumblersofthe lock -will be indicated both to the sense of hearing and to thatof touch, as said balls 9, on the rotation of the knob enter the'openings or depressions 10 in succession and produce a clicking sound,

so ,that the lock can be operated in the dark as, well` as when a dialAis visible to the operator. These features ofthe lock,how

ever, constituteno part of my present invention, being shown, describedand claimed in y prior application, No. 316,511, dated May 12,1906. l

'A spring 6 interposed between the annular .plate: 'a and a disk'14 onthe knob spindle 5 tends to'nrmally maintain the balls 9 in en` gagementwith'the countersunk depressions or openings'lQ, but slight longitudinalmovement of the knob spindle, restricted by the. headof a screwf13 atthe inner end of said spindle, permits such outward movement of the knobas to eiiect withdrawal of the balls 9 from the openings 10, and thelockcan then -be' operated by sight alone.

The disk 1li-'engages a reduced or'flattened portion of the knob spindle5, and it is there fore compelled to turn with the latter, and thusconstitutes a driving disk for the tumblers. "f Y The driving disk 14has a series of-slots 15 anda series ofnotches 16, one for each slot,and with any of the slots '15 may engage a pin n 17 projectin from asupplementary driving disk 19, willich is mounted so as to be free toturn on the htib 7 of the' face plate. Between the main andsupplementary driving .disks are interposed tumblers 20, each ot whichhas a peripheral notch 22 and also al segmental slot or slots 21for-'thereception of the driving pin 17, the length of each slot and therelation of a peripheral notch thereto determining the adjustment of thedierent tumblers necessary in order to bring their notches into line inopening the lock. The supplementary driving disk 19 also has aperipheral notch 22, and therefore acts as a tumbler in the same manneras the tumblers 20. These tumblers, like the disk 19, are free to turnon thehub 7, but are prevented, by washers 23, from imparting motion oneto another except through the medium of the driving pin 17, the washersbeing interposed between the successive tumblers and between the firsttumbler and the supplementary driving disk 19, and being prevented fromrotating by reason'of the engagement of Slotted lugs 24 thereon with al-ug 25 projecting inwardly from the face plate 1.

Between the supplementary driving disk 19 and the face plate of the lockis interposed a bolt thrower 26, which can turn on the hub 7 and is'provided with projecting teeth 27 and 28 forengagement with the boltplate 31, which has in the present instance twobolt lugs 32 and isguided between a ange of the lock plate 1 and 'a slotted rib 34 project`l ving from the inner face of the same;Y the'bolt plate being intendedto lbe movedY in' one direction by the bolt thrower 26, and in theopposite direction by a spring 29 connected at one end to a stud 30 onthe bolt plate 31.l

and at the other end to a the face plate of the lock.

Pivoted to a pin 35 on the bolt thrower 26 is? a lever 36 provided witha dog 37, said lever being acted upon by a spring 38 in such manner thatthe dog 37 has a normal tendency to move inwardly or toward the axisofthe knob spindle. A On a pin40 in. the lock case swings a hooked arm41 which partially embraces the hub 7, as shown in Fa'g. 6, and isnormally 'maintained in contact with said hub by means 'of a spring 42.

A pin 43 on the bolt plate 31 serves as a pivot for a trigger 44, whosefree end, when post 30, secured to the lock is open, is caused, by theaction of a spring 45, to project through a slot 4G in the guide rib 34,as shown in Figs. 3 and G, the end of the trigger thus retaining thebolt plate 31 in the unlocked position againstthe action of the spring29. `When, however, the lid of the box or chest is closed, one of thehasps strikes the projecting end of the trigger '44, and depresses thelatter to suchan extent that lit is disengaged from the outer wall ofthe slot .46 of the guide rib 34 and fails to longer retain the boltplate in .the open position, the spring 29 then moving the holt platefrom the position shown in Fig. il tothat shown in Fig. 2, therebyeil'ecting the ejection of the dog from the notchesl of the tumblers andthe dispersal ol the latter as hereinafter set forth.

'Vhen the lock is locked and the bolt plate `3l projected the partsoccupy the relation shown in Fig. 2, the vinner end of the dog 37resting uponthe peripheries of the tumblers and driving disks, but whenby proper manipulation of the knob 4 the notches 22 of the tumblers anda notch 1G oiE the driving disk have been brought into line with eachotherand with the inner end otthe dog 37, the latter will, by the actionet a spring 38, be caused to enter said notches, and further movement ofthe driving d isk will therefore be imparted to the dog and thence tothe bolt. thrower 26 which carries the same, and consequently to thebolt plate 31 so as to retract the bolt lugs 32, as shown in Fig. 3. l

Then the dog 37 enters the notches ot the driving disk and tumblers, itis brought in front of the inner end of the arm 41, as shown in Fig, S,andas the dog is moved forwardly it carries said-arm 4l with it, the armswinging on its pin 4() until, because oi the different arcs of travelof the arm and dog, they clear each other, whereupon the arm isimmediately restored to its normal position by the action ol the springl2, as shown in ltig. 3, thus bringing under the dog 37 the outer faceot the arm -ll which is jnclined in respect to the are ol'l travel otthe inner end of said dog 37 when the latter .is in engagement with thenotches ot the `thrower, the inner end of the dog 37, will ride on theinclined face of the arm 41 and will be forced by the latter ',out ofthe notches ot' the driving disk and tumblers, and the latter will, bytheir momentum, be dispersed or disarranged to such an extent as tocarry their notches outof line with one another, and thus compel areadjustiment of the tumblers through the medimn of the knob bcfore thelock can be again opened.

In Fig. S -I have illustrated the application of my invention toamordinary l'orm of latch lock having a beveled bolt 32, the lock plate31l having a slot 3l" whereby it is guided on lche pin 40 upon which'thearm 41 is mounted, the action of the lock in other respects being thesame as that of the lock which l have described at length in thepreceding portion ofi this specification. i

I claim l. In a spring lock, the l'omhination of a bolt, notchedtumblers, a dog engaging the same and remaining. in engagement therewithwhen the bolt is retracted, and automatic means independent of thetumblers and acting directly upon the dog to effect ejectment of thesame and permit dispersal of the tumbler-s by rotation of the same whenthe bolt is projected.

2. In a spring lock, the combination of a bolt, notched tumblcrs, a dogengaging the same and remaining in engagement therewith when the bolt isretracted, a bolt thrower carrying said dog,'and means independent ofthe tumblers 'and acting directly upon the dog to effect automaticejectment of the same and permit dispersalof the tumblers by rotation ofthe same when the bolt is projected.

In a spring lock, the combination of a "bolt, notched tumblers, a dogfor engaging the same, anda dog-engaging device which is moved out ofthe way by the dog in the opening movement of the lock and engages andejects said dog when the bglt is 'projected. y

et. In a spring lock, the combination of a bolt, notched tumblers, a dogfor engaging the same, and a pivoted and spring-actuated dog-ejectorvwhich is mgoved out of the Way by the dog in opening the lock, and actsupon said dog to eject the same from the notches of the tumblers whenthe bolt is projected.

5;'In a springlock thev combination of notchedtumblers, a dog forengaging the same, and a dog-engaging device having a free end normallyprojecting into the path .of the dog but swinging in a plane eccentricto said path, whereby it is automatically freed from engagement with thedog as the latter moves forward, said free end of the ejector having acam formation which acts lupon the dog to eject the same from thenotches of the tumblers as it moves backward.

Intestimony whereof, I have signed my naine to this specification, inthe presence of two subscribing witnesses.
